Katana UTML (Ultra Translucent Multi Layered 557 MPa)

Recommended use 1st Bi to 1st Bi upper and lower.

Enamel-like Translucency

Making natural veneers and other anterior prosthetics from zirconia? YES.

KATANA Zirconia UTML is so translucent that light reaches the original tooth color, bringing you the natural result you need. This zirconia has one of the highest translucency levels on the market, as well as a natural color gradient. The next time you plan to fabricate a veneer, think about milling KATANA Zirconia UTML. You will be thrilled using zirconia in a totally new way.

Minimum Wall Thickness of KATANA Zirconia UTML/STML

Design a restoration using the suggested guidelines for minimum wall thickness.

KATANA™ Zirconia UTML is the most translucent among the series recommended for fabricating anterior crowns or laminate veneers. Two different shade types are available: Standard shade and Enamel shade.

Katana STML (Super Translucent Multi Layered 748 MPa)

Recommended use 2nd Bi and 1st Molars.

Well-balanced Translucency and Strength

Do full contour zirconia prosthetics look natural? Yes!

With
KATANA Zirconia STML light is transmitted in the incisal area and blocked in the cervical area. You have the flexibility to make beautiful full contour prosthetics, regardless of the abutment color. It’s a pioneer of zirconia with a color/natural translucency and color gradient. Use
KATANA Zirconia STML for your next full contour prosthetics. The results will be so lifelike, you’ll be eager to fabricate more.

Minimum Wall Thickness of KATANA Zirconia UTML/STML

Design a restoration using the suggested guidelines for minimum wall thickness.

*Thickness only for zirconia without porcelain build-up. Keep 0.8mm in case of porcelain build-up. You can reduce to 0.4mm when finishing with glaze and polish.

Lithium disilicate glass-ceramic block for the CAD/CAM technique

The Material

The IPS e.max CAD blocks are made of lithium disilicate. The characteristic and striking colors of the blocks range from white and blue to bluish-grey. The color is the result of the composition of the glass ceramic.

Thanks to an innovative manufacturing process, IPS e.max CAD features an impressive homogeneity and can be easily processed using the inLab or Everest system. The strength of the material in the pre-crystal «blue» phase can be compared with that of other glass ceramics currently available on the market.

After the blocks have been milled, the material undergoes a crystallization process in the P200 or EP 600 Combi furnace. The crystallization process results in a change of structure, which imparts the glass-ceramic with a strength of 360 MPa and the actual optical properties, such as shade, translucency and brightness.

The tooth-shaded IPS e.max CAD frameworks form the ideal basis for the fabrication of aesthetic crowns and anterior bridges, which are completed with the optimally coordinated veneering ceramic IPS e.max Ceram.

The Highlights

Efficient, economical processing due to easy grinding properties

High final strength of 360 MPa

Easy and fast crystallization (850 °C, 30 minutes)

Crystallization without shrinkage and complex infiltration processes

Lifelike and translucent aesthetics

Can be processed using 2 CAD/CAM systems: inLab (Sirona) and Everest (KaVo)

Zirconium oxide block for the CAD/CAM technique

The Material

IPS e.max ZirCAD blocks are made of yttrium oxide-stabilized zirconium oxide. In the partially sintered, «chalk-like» state, IPS e.max ZirCAD can be easily milled in the inLab (Sirona) unit. The milling process is conducted by enlarging the framework by 20 %.

During the subsequent controlled sintering process in the Sintramat high-temperature furnace, the frameworks shrink to their final size and are imparted with the high fracture strength and high fracture toughness.

A specially designed fluorescent zircon liner provides an optimum bond and is used to apply the basic shade on the frameworks. Subsequently, IPS e.max ZirPress is pressed in a fully or partially anatomical manner onto the crown copings and bridge frameworks or IPS e.max Ceram layering ceramic is used to apply the veneers.

The Highlights

Extended range of indications thanks to the outstanding strength of 900 MPa and high fracture toughness

Optimum bond and application of the basic shade with the specially developed IPS e.max Ceram ZirLiner
